Warning problems of the 2019 Subaru Forester

Improper glass installed by safelight adas unable to be calibrated.

The check engine light went on and the diagnostic code read was p26a3, engine coolant bypass valve is failing in my 2019 Forester, which only has 46,000 miles on it. Subaru was aware that this part was defective in the 2019-2021 models, because in Feb of 2022 the part was replaced and a service bulletin 09-80-21 was issued with instruction for replacing the part, but did not issue a recall, despite this problem causing the advanced safety features to stop working and directly affecting the proper functioning of the engine. My car is just out of warranty, and the quote to have my mechanic replace the part is almost $1200 which I am unable to afford and do not feel I should have to pay for. Subaru should be help to account for this issue.

I am concerned as my car was safely parked, once I started it and it said eyesight off, flashing s symbol, the heat thermo stat changes back and forth from hot and cold, car is not warming up and check engine light came on. I am very concerned as it is the winter, and I have my baby in the car. Please advise. This seems very unusual and never happened before. The vehicle have around 23k miles.

All of a sudden, the eyesight and collision prevention stopped working, the check engine light came on, the blue light thermostat indicator came on. We had no heat. The flashing "s" (sportsmode indicator) came on. We were driving on the highway and still over an hour from home. It was snowing, we could not adequately clear the windshield of fog so our visibility was severely compromised. We lost all eye sight capability which meant that we were vulnerable if there was ever a crash or an obstruction in the roadway.

4 days ago my check engine light came on. In my car, when this happens, it disables all eyesight features - collision warning, lane departure warning, etc. Work hours being what they are, I drove home that night and back to work the next day with it on. I managed to get it scanned when it popped a code for the coolant bypass valve. Searching that code online lead me to dozens and dozens of forums, posts, stories of the same code popping up on other 2019-2020 Subaru's. They all had to take it in for a hefty repair. It also led me to a service bulletin issued last year, which showed that Subaru had rebuilt the tcv so it could withstand corrosion, unlike the previous version. So naturally I took it into my local dealership to have it looked at, and sure enough - the tcv needed to be replaced. Why hasn"t this part been recalled yet??? given there is no thermostat on my cars dash, I would have no clue whether my car was overheating due to this faulty valve, until its too late. It seems like this is a big potential safety issue that Subaru needs to address, and someone needs to force their hand.

I recently bought this vehicle (used) with ~1900 miles. After 1. 5 months of owning the vehicle, I suddenly had several warning lights as well as systems disabled within the vehicle. The first time this occurred I was about 2 hours into a drive, and suddenly my eyesight disabled, check engine light came on, cruise control disabled, lane departure disabled, collision warning and automatic braking disabled. After pulling over to inspect, I also realized my trunk would no longer open. I took it to a dealership who said it was due to low battery voltage—despite there being no spectacular incidents to drain the battery since I purchased the vehicle. They recharged the battery and the problem was temporarily fixed. However, once I retrieved my vehicle from the dealership the check engine light and disabled features were still prevalent. I once again had them recharge the battery—despite there again being no events causing the battery to drain—to which the problem was solved. Again, about an hour into my drive back home, the check engine light and features suddenly disabled. This is detrimental to my safety as a driver—as every safety feature suddenly disables without warning during my drive.
